For my AirBnB Income Calculation spreadsheet, I take the average of the area (no filter) through a quick AirBnB search without dates, then I take a filtered average of the area (specific to my rental: i.e. number of rooms, bathrooms, beds, pets allowed, etc.) and use the average of both minus 10% of the Max of the averages (because I want to be competitive in the market and to provide conservative estimates).

Search filtering includes any combination of non-owner occupied, out-of-state owner, vacant, MLS status, distressed and so on.

I'm just starting out with learning about real estate, so I'll just read books recommended here on BP and move on to other books later when I can better filter through the information to find what's useful.

It's pretty common for REOs to smell like they have a mold problem when in actuality they don't -- once you get the HVAC running with a decent filter, the smell will go away.That said, if there is a mold problem, the first course of action is going to be to determine what the source of moisture is, and get it remediated.
